The state space is finite or countable for example the non- negative integers {0, 1, 2,…}. – Continuous-state process. Telcom 2130. 3. Continuous state process. •

• formal deﬁnition of stochastic processes. 1.1 Revision: Sample spaces and random variables Deﬁnition: A random experiment is a physical situation whose outcome cannot be predicted until it is observed. Deﬁnition: A sample space, Ω, is a set of possible outcomes of a random experi-ment. Example: Random experiment: Toss a coin once.

Proposition 1.10. In the description of such a stochastic process we must know thedistribution function of the stochastic process, i.e.

Any realization or sample path is also called a sample function of a stochastic process.

Thanks a lot. Examples of Stochastic Process, Markov Chain, M/M/* Queue .

Examples: random walk; Gaussian distribution: for variables, vectors and processes, non-degeneracy, stationarity, closeness under 2-mean convergence.

In the description of such a stochastic process we must know thedistribution function of the stochastic process, i.e. P {X (t1) x1X (t2) x2··· X (tn) xn} for every t1,, tnT, and everyx1,, xnR, for everyn N. ing set, is called a stochastic or random process. We generally assume that the indexing set T is an interval of real numbers. Let {xt, t ∈T}be a stochastic process. For a ﬁxed ωxt(ω) is a function on T, called a sample function of the process.

A stochastic process is a collection or ensemble of random variables indexed by a variable t, usually representing time. For example, random membrane potential fluctuations (e.g., Figure 11.2) correspond to a collection of random variables V(t), for each time point t.

2 Queuing Network: Machine Repairman Model Similar to Example 1 in lecture notes “random” 9 Another Markov Chain Example For example, we all feel that we understand ﬂipping a coin or rolling a die, but still accept clear at the moment, but if there is some implied limiting process, we would all agree that, in the limit, certainty and impossibility correspond to probabilities 1 and 0 respectively. Stochastic process is the process of some values changing randomly over time. At its simplest form, it involves a variable changing at a random rate through time. There are various types of stochastic processes.
